It’s probably not too important to choose a service that you think you can trust fully, because that trust might be broken at some point. But having an identifier that can be swapped to different backends, so people can find you again when the host inevitability changes, is a stronger strategy. I think the importance of owning domain names will increase, and using those as the canonical identifier of a project will give it more permanence. The procedures for seizure and censorship with domain names are better established and understood.
